GAUGE COCK.

Application filed May 3,

My invention relatesto gaugecocks and more particularly to gauge cocksand provi-.

sion for raising the cocks; and the object is to provide improved gaugecocks and 1mproved means for operating the gauge cocks cock shown in theso that a person at any ordinary location below the gauge cock can raisethe cock for test- 7 ing the amount of water in the boiler, thisinvention being an improvement on the gauge patent granted to me onMarch 11, 1924, No. 1,486,162. Other objects and advantages will befully explained in they following description and-the invention will bemore particularly pointed out in the claims.

Reference is bad to the accompanying drawings which form a part of thisapplication. 1

Fig. 1 is a side elevation of the cock provided with the handle liftingdevice, and showing in dotted outline the position of the valveoperating means when the gauge cock is opened.

Fig. 2 is a side elevation of the gauge cock,

showing the opposite side of the cock from that shown in Fig. 1.

Fig. 3 is a detail View of the valve, being an inner face view.

Fig. 4 is a side elevation of the same.

Fig. 5 is a longitudinal cross section of the valve and handle.

Fig. 6 is a broken sectional view, showing the valve construction.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The drawings showa steam discharge nozzle 1 provided with a steampassage 2. A handle 8 has a valve chamber 4 therein which iscylindricalin form and the handle has a slot 5 which extends to and communicateswith the chamber 4; through a slot'6 in the.

part of the handle which surrounds the'valve 7 The slot 6is elongated topermit the swinging of the handle 3 relative to the nozzle 1,

so that the nozzle will be engaged by the valve 7. The discharge nozzle1 has an up standing crane member 8 which projects through the slot 5and serves as a bearing for anchoring the handle 3 to the nozzle 1 by apivotal connection, a cotter pin 9 forming the connection.

The valve used herein is a composite valve,

having a flanged head 10 of metal or composition metal and a reducedcylindrical body 11 and a cylindrical fibre composition valve 1926.Serial releases.

member? which is mounted on the body 11.

The Valve member is preferably made of hardened fibrous material. Thecylindrlcal portion of the valve lncluding parts 11 and 7 constitute thebearing member of the Valve to be engaged by the nozzle tip 15. Thevalve is revoluble in its chamber by loos'ening'the nut 13 which issecuredto the bolt 12 and normally bears against the valve member.

The valve member 7 may be secured to the.

cylindrical extension 11 by lugs '14 struck from the member 11 and bentoutwardly into cavities in the end of the valve member 7. The valvemember 7 rests normally, against the tip 15 of the nozzle member 1. Whenthe peripheral surface of the valve member be comes worn where thenozzle tip 15 bears against the valve member, the nut 13 may be loosenedand the valve turned slightly to bring an unworn portion against the tip15. This may be continued until the entire peripheral surface of thevalve has beenused.

The gauge cock is provided with means for lifting the handle for testingthe water level or the amount of water in a boiler from positions belowthe gauge cock. A chain 16 is connected to the handle 3 and may beextend ed through the crane member 8 and down to the position below sothat a person on a lower floor may test the water in the boiler withouthaving to go up to the boiler. The bearing surface 17 in the crane 8should be curved, as shown in Figs. 1. 2, and 5 so that the chain 16will move back and forth with as little friction as possible.

What I claim is, 1. A gauge cock comprising a handle provided with acylindrical valve cavity therein and having a slot in the operative endthereof and an elongated slot opening into said cavity, a cylindricalvalve mounted in said cavity and provided with a flanged headbearingagainst the outside of said handle, a bolt rigid with said handle andprojected through said valve, a nut for binding said valve rigid withsaid bolt, a steam discharge nozzle adapted to project'into saidelongated slot against saidvalve, and'provided with an upstanding craneoccupying the slot in the end of said handle and provided with anopening therethrough, and a chain connected to said handle and projectedthrough theopening in said crane. p e e 2. A gauge cock comprising ahandle provided with a cylindrical valve cavity therein and providedwith a slot in the operative end leading to said cavity, a steamdischarge nozzle adapted to project into said. slot and into saidcavity, means for pivotally connecting said handle to said dischargenozzle, a bolt in said cavity rigid with said handle, a Valve composedof a combined flanged head for engaging said handle and a bearing memberconsisting of a reduced. central cylindrical extension in the centralportion of said cav- 10 ity and a hard libre cylindrical nozzle engagingmember mounted on said extension, a nut engaging the end of said boltfor binding said Valve rigid therewith, a bearing crane on said nozzle,and a chain eperativcly connected to said handle and extended over saidcrane for lifting said handle.

In testimony whereof, ll set my hand, this 31. day of March, 1926.
